The family, along with Christina‘s eight-year-old son Max, celebrated the occasion with a Super Mario Bros. themed birthday party.

Christina dressed up as Mario while Matthew opted for a Luigi costume. Summer looked super cute in her Mario costume as well!

“I get so happy seeing the strong and loving relationship they have, and I know she’s getting the safe environment I never had growing up,” Christina told Us Weekly about the bond that her daughter and fiance have.

Christina also said that Summer is growing up to be “a bit more of a tomboy.”

The track – written by Sia and produced by Nelson George – is set to be featured on the upcoming soundtrack to Baz Luhrmann‘s new Netflix series The Get Down, which officially premieres tomorrow (August 12)!

Christina is proudly donating 100% of the song’s proceeds for the next three months to the National Compassion Fund to directly benefit the Orlando shooting victims and their families – Watch the stunning performance below!

The 35-year-old entertainer is proudly donating 100% of the song’s proceeds for the next three months to the National Compassion Fund to directly benefit the Orlando shooting victims and their families.

“The horrific tragedy that occurred in Orlando continues to weigh heavily on my mind. I am sending so much love and so many prayers to the victims and their families. Like so many, I want to help be part of the change this world needs to make it a beautiful inclusive place where humanity can love each other freely and passionately,” Christina said in a statement on her official website. “We live in a time of diversity, in a time of endless possibilities, in a time where expression of oneself is something to be celebrated. And I am left wondering how people filled with so much love could be taken by so much hate. Though there is such heavy sadness I believe that there is much more love in the world than we know. We need to learn to love again, we need to learn that one person does make a difference; we need to keep love in our hearts. As Nelson Mandela once said, ‘No one is born hating another person because of the color of his skin, or his background, or his religion. People must learn to hate, and if they can learn to hate, they can be taught to love, for love comes more naturally to the human heart than its opposite. We all have the choice to spread love, encourage individuality and make a difference to others – we are all in this together, as one, united in love.”
